Astrochemistry of H3+

Our group uses astronomical observations of H3+ to constrain the cosmic ray ionization rate in diffuse clouds.
CH5+

New Interstellar Molecules

A major motivation for the group's research is the discovery of new interstellar molecules. We want to use these molecules as probes of astrophysical conditions.
